Brief and to the point and, most importantly--capturing the right context. Don't waste time with fluff and irrelevant details bc someone still has to sit there and listen to it. *WHY* did you post the image? What information does it convey? That's the context missing that you need to provide.

That's going to be an interesting balance to try and meet, looks like I have a bit of work ahead of me to master it but well worth it
